我试图用TMS320VC5509A驱动HT1621,可是不成功。
#define CS_0 GPIO_RSET(IODATA,temp&0x0fe)
#define CS_1 GPIO_RSET(IODATA,temp|0X001)
#define WR_0 GPIO_RSET(IODATA,temp&0x0fd)
#define WR_1 GPIO_RSET(IODATA,temp|0X002)

#define DA_0 GPIO_RSET(IODATA,temp&0x0fb)
#define DA_1 GPIO_RSET(IODATA,temp|0X004)
我担心是这几句有问题。
不知道5509有没有对IO口位操作的函数。
请大神指教，谢谢！

Jacktang

只是建议

确保宏定义或函数调用正确，且用的端口和引脚编号与硬件设置匹配。

检查全局变量temp，它的值在代码中好像并没改变吧

chenbingjy

谢谢！我改成类似这样就好了

temp&=0xfe;
     GPIO_RSET(IODATA,temp);
